13. Synalpheus carinatus de Man, var. binongcensis n. 



Station 220. Auchorage ofï Pasir Pandjang, west coast of 

 Binongka. Depth 278 M. 



Rostral carina not notched at the boundary between the gastric 

 and cardiac regions. Supraorbital spiues slightly convergent and less 

 distinctly turned upwards than in the typical species. The length 

 of the telsou equals just 4-times the width of posterior margin, 

 greatest width 2,6-times as wide as posterior margin (in an adult 

 female of the typical species these numbers are respectively 3,41 

 and 2,2) ; spinules of upper surface inserted a little more backward. 

 Carpocerite exceeding the anten nular pedancle by half the 

 third article. 



Ova 1,2 m.m. long, in the typical species 0,9 — 1 m.m. 



One female, long 25 m.m., collected on a Comatula.

Station 220. Auchorage off Pasir Pandjang, west coast of 

 Binongka. Reef. 



Rostral carina not notched, carinae of supraorbital spines in- 

 distinct. Telson 4,44 — 4,8-times longer than the width of pos- 

 terior margin, proportion between the greatest width and that of 

 posterior margin 2,6 — 3 ; anterior pair of spinules of upper sur- 

 face inserted just in front of the posterior third. 



Second, 3rd and 4th segment of carpus of 2nd legs of equal length. 



Ova very small, 0,4 — 0,48 m.m. long (in the typical species 

 0,9 — 1 m.m.).
